JOHN L. WHITEHURST Ann c AnLns BY MESNE ASSIGNMENTS, To onN LABELING-MACHINE.

To all whom it may concern:

.Be it known that we, JOHN L. WHITE- HURST and CHARLEsI-I. WILD, citizens of the United States of America, residing at Baltimore, Maryland, have invented certain Improvements in Labeling-Machines, of which the following is a specification.

This invention relates principally to a novel construction of a labeling machine, wherebycertain parts of the same which have to be adjusted or changed in position to admit of the application of labels to cans of different diameters, are so combined as to form an entirety which can be moved in and by a single adjusting operation, as will hereinafter fully appear..

In the further description of the said in V vention which follows, reference .ismade to the accompanying drawings, forming a part hereof, and in which Figure 1 is'an exterior side elevation of the improved machine, or of such parts thereof, as are involved in the present invention; and Fig. 2 a plan or top view of i of certain parts of the machine.

Fig. 6 is a view of certain parts shown in Fig. '5 looking in the direction indicated Figs. 7 and 11, inclusive views of parts of the machine, and hereinafter described. I i

Referring now to the drawings, 1, 1 are straight bars which form the frame of the machine, and 2 represents a part of the stand which supports the frame, 3- and 4 are pulleys which are tight on i the shafts 5 and 6, situated respectively a at class.

9, Stare-guide rails which extend the entire'length of the machine between which the cans are rolled by the conveyer belts. These rails'are supported at the forward end of the machineby brackets 10 which are fastenedto the bars 1, and at the rear end, by the standards 12 which are also seas best shown in Figs.

cured to the bars 1, 1 and 11. The immediate means of connecting the guide railsto the brackets and standards consist'of rods 13 one of which is shown inFig.11.' 3 I The guide bar 9, at oneside of the machine is'fiXed as is usual, while at the other side it is adjustable laterally of the machine to provide for cans differing in placed between the nuts 16 and the supports, which upon being pressed, overcomethe tension of the springs 19, and cause the bar to be drawn outward, as will be readily understood. i

As it is necessary to vertically adjust the lower "lay of .--the 'conveyer belts," to suitthe diameter of the cans to be labeled, the shaft in stands 21 whoselower ends arefturned to'fit loosely-in the brackets 10, and when adjusted, they are held by pins 6. i To admit of the vertical adjustment of the conveyer belts at the delivery endof the 'machine, they are made to pass under tension pulleys 23 whose shafts'are' journaled" in bearings 24 inbosses formed on the standards =12.

From thexforegoing description ityy "be understood that "the yoke '40, carryin th bridge 46 with its arched plate 49 nd i the . I 1 .1 im an ent ret hie .fli .i;$ is :ept.,... ad ustment "longitudinally of "the" machine;

of 4 Y 115 p st vbe e p lie t belt 77 1h its moyeinent toward 'an d'goyer thereby adapting the machine for labeling cans of various diameters requiring labels of diiferent lengths, by means of the handlever 43, in a single operation of the same,

thus obviating the necessity of separate adjustment ofthe parts, which separate adjustment is not only troublesome, but requires expert knowledge rarely met with in operators of labeling machines, and that the adjusting operation after a stack of labels of the required length have been placed on the table 53 with its forward end closely in contact with the permanent stop 55, is to bring the movable stop 57 up to the stack by means of the hand-lever 43.

We claim as our invention:

1. In a labeling machine, the combination with the bed thereof, of practically fixed devices to apply an adhesive to cans and a label stop all situated at the entrance end of the machine, a paste pot with its pasting belt, a second label stop, a label curling rod, and a compression pad, the said elements bein united so as to constitute an entirety,

and means whereby the said entirety can be shifted longitudinally of the bed, substan: tially as specified.

2. In a labeling machine, a pair of standards movable longitudinally of the frame carrying a paste pot with its paste-applying belt, a bridge having a pendent label stop, a label curling rod, and a compression pad, combined with an actuating yoke and a hand lever whereby a joint movement of the said pasts can be effected, substantially as specifie 3. In a labeling machine, endless conveyer belts for the cans horizontally placed vertically adjustable elevated bars carrying tension rollers for the belts, combined with inclined bars with pulleys at their end which support the ends of the horizontal bars, whereby in the sliding of the inclined bars the vertical height of the horizontal bars is controlled.

l. In a labeling machine including means for applying an adhesive to the cans, and a label stop, all situated at the entrance end of the machine, the combination of longitudisaid paste applying device,

' in a fixed part of the machine,

nally movable means constituting a unitary paste applying device, a lever fulcrumed in a fixed part of the machine, and a link connection between said lever and a member of whereby said paste applying device as an entirety, may be moved longitudinally of the machine, substantially as specified,

5. In a labeling machine, the combination with the bed thereof of label pasting device embracing a paste pot, a pasting belt and a label compression pad, ofa lever fulcrumed and a link connection between saidlever and a memberof said paste applying device, whereby said device, as an entirety, may be moved longitudinally of the machine, substantially as specified.

6. In a can labeling machine including means for applying an adhesive to the cans,

and a label stop, all situated at the entrance end of the machine, the combination of paste applying devices comprising a standard, a paste pot carried thereby, a yoke, a bridge borne by said yoke and having an arched plate and a sponge block, said paste applying devices constituting an entirety or a uni tary structure, a lever fulcrumed to a stationary part of the machine, and a link connecting said lever to an element of said movable paste applying entirety or unitary structure, whereby longitudinal movement of the latter relatively to the machine may be efiected, substantially as specified.

7. In a labeling machine, label pasting devices comprising a paste pot, rollers within the same, pulleys, and a pasting belt passing over said rollers and pulleys, combined with x a lever and link connection between a fixed part of the machine and said'pasting devices whereby said pasting devices as an entirety may be moved longitudinally of the machine, substantially as specified.
